Indoor membership

My brother and i both play tennis but recently it gets cold and icy at our place and we want to move it indoor. The membership thing, can i just get one and go hit with my brother? Or do we have to obtain both? If i just get one, and my brother can go hit free with me as if hes my "trainer", that will be awesome. Does anyone have any experience about this membership thing?

For indoor courts where I live, you don't pay for a membership, you pay for court time. For example, you would call ahead and ask for an hour of court time at 8:00 PM. Usually clubs have indoor rates which range from 12-25 dollars an hour, depending on the time.
